What is the first generation of operating system?
First generation of operating systems were developed around early 50s to meet the hardware evolution of the time. During this period, the mode of operation was called closed shop where operators would select , run jobs and select another jobs.
Later, a development of mono-programmed OS which eliminated some of the human intervention in running jobs came into play as systems were designed to be operated as batch processing system.
The inherent problems with the first generation were inefficient use of system resources ( which was evident in slow CPU performance) and system protection.
What are the main purposes of of an operating systems?
It is used to operate the computer well besides we need a software to run in our system . run software and games we need the help of the o/s ( win xp,win7, win vista etc)
Which is more important application or operating software?
Operating system is more important than the application software, in the sense that the operating system is the mother of all software that are to run on the computer. without the operating system, it is impossible for the computer to run. operating system provides a platform for all other software to be installed on. it is actually the main software that supports all other software.
What is the main character of the Linux Operating system?
Linux is, as you noted, an operating system. It is not a game so it does not have a main character. However, different distributions have different mascots. For example, the mascot for SUSE Linux is a lizard of some sort. The mascot for Linux in general is usually stated to be a penguin named Tux
What is the command to delete?
Delete command is a DML. Syntax of delete command is delete from table_name where <>; It is to delete content of table.
Can you install more than one operating system in a machine and can you give an example?
Yes. You need to create a Primary partition and then a secondary partition. You'll want to install your main OS on the Primary partition (Windows, Mac, Linux, Novell, ect.) and then put the other OS on the secondary partition (I typically see Linux.) Then you can choose to boot from the primary partition or the secondary partition in the BIOS. The bigger the hard-drive you have the better, and I wouldn't try it with anything less than 100 gigs.
Is LimeWire 4.18.8 compatible with Mac OSX Snow Leopard?
To ensure full compatibility with Mac OS X 10.6 (Snow Leopard) it is best to install the latest version of LimeWire 5.3. (See links below)
Yes, Windows 7 is an operating system developed by Microsoft.
so as to infom the processor of what it ought to do
A P2P network needs network operating system software installed on every node?
False. In P2P network network is only set up once, other computer just have to connect to it.
What are the typical elements of a process image?
User data: Modifiable part of user space. May include program data, user stack area, and programs that may be modified.
User program: The instructions to be executed.
System Stack: Each process has one or more LIFO stacks associated with it. Used to store parameters and calling addresses for procedure and system calls.
Process control Block (PCB): Info needed by the OS to control processes.
I assume OS means Operating System ... in computers.
Here are some

What is the most recent Windows Operating System software available?
Windows 8 for home, business and portable is the most recent Windows Operating System software. It was released in 2012 and features a new touch interface and is designed to be more compatible with mobile devices such as tablet and notebook computers.
successor to iPhone 11, no innovative new features actually compared to iPhone 11, but get some redesign and enhancements like A14 chip, 5G connectivity, triple-lens 3D cameras, AirTags....get more detailed info from Mac tech sites like macxdvd, macrumors, appleinsider.... if you need
Why did Apple choose to name their computer Macintosh (Mac)?
Apple employee Jef Raskin is responsible for coining the machine after his favorite variety of apple, smartly tying the whole fruit theme together.
What is the difference between operating system software utility software and application software?
- An operating system is the software that bridges the gap between the system and the user.
- Utility software performs actions essential for protecting, guiding, securing, and storing information or data appropriately in the system.
- Application software manages specific actions, for example, browsers, word processors, etc.
Can you open a website in dos operating system?
MS-DOS and most clones do not include a web browser in their core utilities. There are a few web browsers available for MS-DOS, but setting up and installing a packet driver for a network card in DOS is only slightly less difficult than cutting off your arm with a toothpick. The web browsers available also don't render most modern web pages correctly, and the performance is abysmal.
Would you set up a GUI on a server system?
Not sure what this means. But SSR is a relatively new but extremely important feature of modern web apps.
Advantages layered architecture operating system?
The O.S has been divided into different layers and each layer has mentained some hierarchy.
What was the first operating system?
The earliest computers did not use operating systems; a simple loading program was loaded into the computer - via front panel switches or punched tape, the loading program would load the actual program to run. The program would take over the entire machine until it halted or was interrupted by the operator.
This process of loading programs from storage was automated, to some extent, in the 1950s and MIT may be able to claim the earliest such system in 1954 (see attached link).
This is one of the things no one will ever know for sure. When I developed software for the IBM 704 in conjunction with a missile guidance project in 1957, I had never heard of an operating system but I eventually realized that that's what I had created. It's written up in the Annals of the History of Computing, Volume 11 (1989). I can't say that it was first, but it was early, and I don't know any older ones.
In 1961, Burroughs introduced the MCP (Master Control Program) for its B5000 mainframe computer. These early operating systems were little more than loaders. With the advent of high speed disk drives, virtual memory systems and disk control systems became more widely used.
In 1969, Unix was being developed. Unusually for the time, Unix was designed to run on different machines, small device drivers were written for specific hardware, but the bulk of the code was unchanged.
The first microprocessor operating system was CP/M; as with Unix by separating the hardware dependent parts of CP/M from the majority of the code, it made it easy to port CP/M to different hardware platforms (although it was written for the 8080 family of microprocessors).
What is the importance of operating system?
An operating system provides an interface between the hardware and the user. It allows us to use computers without having to know how to program them.
Define deadlock in operating system?
In order for deadlock to occur, four conditions must be true.
- Mutual exclusion - Each resource is either currently allocated to exactly one process or it is available. (Two processes cannot simultaneously control the same resource or be in their critical section).
- Hold and Wait - processes currently holding resources can request new resources
- No preemption - Once a process holds a resource, it cannot be taken away by another process or the kernel.
- Circular wait - Each process is waiting to obtain a resource which is held by another process.
What operating system does IBM use?
IBM System z servers are supported by a multitude of operating systems, such as z/OS, z/VSE, z/TPF, Linux on System z and the z/VM hypervisor.
